(Submit a file with a maximum size of 1 MB.) y P d 1 0 l i (a) Show that the electric field at P, a distance d from the rod along its perpendicular bisector, has no x component and is given by E 2k sin(@)/d. (b) Using your result to part (a), show that the field of a rod of infinite length is E- 2k1 d
